Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624062, here are decompositions:

  • 59 + 31624003 = 31624062
  • 61 + 31624001 = 31624062
  • 73 + 31623989 = 31624062
  • 79 + 31623983 = 31624062
  • 83 + 31623979 = 31624062
  • 103 + 31623959 = 31624062
  • 109 + 31623953 = 31624062
  • 131 + 31623931 = 31624062

Showing the first eight; more decompositions exist.
